The EU AI Act follows a phased implementation approach with critical milestones starting February 2, 2025 (prohibited AI bans) through August 2027 (full high-risk system compliance).

Organisations face potential fines up to €35 million or 7% of global turnover for non-compliance, making early preparation essential for maintaining market access and avoiding severe penalties.

Time is running out for organizations to prepare for the European Union’s groundbreaking Artificial Intelligence Act. As the world’s first comprehensive AI regulation, the EU AI Act doesn’t just flip a switch—it follows a carefully orchestrated timeline that gives organizations specific windows to achieve compliance.

Understanding these critical deadlines isn’t just about regulatory conformity. It’s critical for maintaining access to the European market and avoiding penalties that can reach into the tens of millions of euros.

The Phased AI Act Approach: Why Timing Matters

The AI Act entered into force on 1 August 2024, and will be fully applicable 2 years later on 2 August 2026, with some exceptions:

• Prohibitions and AI literacy obligations entered into application from 2 February 2025

• The governance rules and the obligations for general-purpose AI models become applicable on 2 August 2025

• The rules for high-risk AI systems – embedded into regulated products – have an extended transition period until 2 August 2027.

This staggered implementation recognizes the varying complexity of compliance requirements across different AI risk categories. It also provides organisations with time to adapt their systems, processes, and governance structures to meet the new regulatory standards.

Critical Deadlines: Your AI Act Compliance Calendar

February 2, 2025: Prohibited AI Systems Ban Takes Effect

✅ Already in Effect

As of February 2, 2025, AI systems deemed to pose “unacceptable risks” became strictly prohibited. This first wave of enforcement targets the most dangerous AI applications, including:

• Manipulative AI: Systems that deploy subliminal, manipulative, or deceptive techniques to materially distort behavior
• Social Scoring: AI systems that evaluate or classify individuals based on their social behavior or predicted personal characteristics
• Predictive Policing: AI systems used to predict criminal behavior by profiling individuals
• Real-time Biometric Identification: Facial recognition systems in publicly accessible spaces (with limited law enforcement exceptions)

What Organizations Must Do Now:

• Immediately cease use of any prohibited AI systems
• Conduct urgent audits to identify potentially prohibited applications
• Implement AI literacy training programs for employees involved in AI development and deployment

August 2, 2025: General-Purpose AI Models and Governance Rules

On August 2, 2025, governance obligations for GPAI model providers will become applicable. This deadline primarily affects providers of foundation models like large language models that can be adapted for various downstream applications.

Key Requirements Include:

• Technical documentation and transparency obligations
• Copyright compliance under EU law
• Training data summaries and content disclosure
• For systemic risk models: adversarial testing, incident reporting, and cybersecurity protections

Critical Actions by This Date:

• Designate national competent authorities (for Member States)
• Establish governance frameworks for AI oversight
• Implement penalties and enforcement mechanisms
• Begin GPAI model compliance documentation

August 2, 2026: High-Risk AI Systems (Annex III) Full Compliance

This represents the most significant compliance milestone for the majority of organizations. On August 2, 2026, the EU AI Act will become generally applicable and requirements around “high-risk AI systems” will go into effect.

High-Risk Systems Subject to These Requirements:

• Biometric identification and categorization systems
• Critical infrastructure management (energy, transport, water)
• Education and vocational training systems
• Employment, worker management, and recruitment tools
• Essential private and public services access systems
• Law enforcement applications
• Immigration, asylum, and border control management
• Administration of justice and democratic processes

Comprehensive Compliance Requirements:

• Rigorous conformity assessments before market placement
• Quality management systems and technical documentation
• Data governance and training dataset management
• Human oversight and transparency requirements
• Accuracy, robustness, and cybersecurity measures
• Post-market monitoring and incident reporting
• Registration in EU database systems

Member State Obligations:

• Member States shall ensure that their competent authorities have established at least one AI regulatory sandbox at national level
• Implementation of penalty frameworks and enforcement mechanisms

August 2, 2027: Extended Compliance Deadline for Regulated Products

AI systems that fall within this category have an additional 12 months from the date of general applicability, with full compliance required by 2 August 2027. This extended deadline applies to:

• High-risk AI systems embedded in regulated products (medical devices, automotive systems, aviation equipment)
• AI safety components requiring third-party conformity assessments
• Providers of GPAI models placed on the market before 2 August 2025 must have taken the necessary steps to comply with the obligations laid down in this Regulation by this date.

The High Stakes: Understanding EU AI Act Penalties

The financial consequences of non-compliance are severe and designed to be genuinely deterrent. The heftiest fines are imposed on operators for violations related to prohibited systems of up to €35,000,000 or 7% of worldwide annual turnover for the preceding financial year, whichever is higher. Here’s the penalty structure by violation type:

Tier 1 – Maximum Penalties (€35M or 7% global turnover):

• Using or distributing prohibited AI systems
• Punishments for failing to comply including a fine worth as much as 35 million Euros ($37 million) or 7% of global revenues, whichever is higher

Tier 2 – High Penalties (€15M or 3% global turnover):

• Non-compliance with high-risk AI system obligations
• Violations of provider, deployer, importer, or distributor requirements
• Breaches of general-purpose AI model obligations

Tier 3 – Moderate Penalties (€7.5M or 1% global turnover):

• Providing incorrect, incomplete, or misleading information to national authorities or notified bodies

Special Considerations for SMEs
Small and medium enterprises, including startups, receive some protection with fines capped at the lower threshold rather than the higher amount between percentage and absolute value.

Global Reach: Why Non-EU Organisations Must Pay Attention

The EU AI Act’s extraterritorial application means geography provides no protection. The regulation applies to any organization whose AI systems produce outputs used within the European Union, regardless of where the organization is headquartered or where the AI system operates.

Examples of Global Application:

• U.S.-administered qualifications such as the Test of English as a Foreign Language (TOEFL) will find themselves covered under the AI Act. Those undertaking TOEFL in Europe have their answers scored in the U.S. by a process that utilizes both AI and human effort
• Cloud-based AI services accessed by EU users
• Software products distributed in EU markets containing AI components
• International companies with EU subsidiaries or customers.
